MACHINEZFOR MOLDING OR SHAPING CONFECTIONERY AND OTHER PLASTIC MATERIALS.

SPECIFICATION forming part of Letters Patent No. 279,131, dated June 12, 1883. Application tiled January 2l), l. (Nn'modol.)

To all whom it may concern: e

. Be it known that l, OLIVER It. CHASE, 'of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and usef'ul Improvements in Machines for Mold ing or AShaping Confectionery and other Plastic lB'Iaterialsyof which the following, taken in conneetion'with the accompanying drawings, is a specification.

My invention is especially adapted for use in the manufacture of confectionery, and is designed for decorating or. ornamenting rods or sticks of confectionery while they are being formed from sugar-paste; and it consists of certain arrangements and construction of mechanism by which lines or stripes of paste of various colors maybe placed/upon the exterior or interioiiot'hpaid stick or` column of `illlimloest 'understood byv reference to the description ofthe drawings, and the claims to be hereinafter given.

In the drawings, Figure l is a central vcrtical section of an apparatus embodying my Fig. 2 is a horizontal Section on line w w on Fig. 1. Fig. 3 is avertieal section on linema' on Fig. l. Fi 4 is a partial vertical section enlarged, and illustrating the method of introducing lines or stripes to the interior of a column of plastic material. Fig. is a sec tion of the Same on line y 1/ on Fig. 4. Fig. 6 isa section on line c c ou Fig. 4. Figs. 7 and 8 are enlarged end views of two finished Sticks of material, illustrating different arrangements of stripes, and Fio. 9 is a partial vertical section corresponding t'o Fig. 3, and illustrating a method of 'coating the entirev surface-of a stick of plastic material. 4

A, B, and G are three vertical cylinders arranged side by side, with their upper ends firmly secured in the plate D. Each cylinder is provided at its open upper end with a short fiinnel, e, to facilitate the introduction of paste thereto, and contains at or near its lower end a screw, E, for feeding the paste downward, said screws being secured upon the lower ends of the three vertical shafts E E E, having bearings in the horizontal bar F, and provided at their upper ends with the bevel-gears El E2 E2, as shown.` Each of said shafts E is provided with a collar, d, secured thereon beneath the bar F, said collars serving to prevent the shafts 'E' E E from being thrust upward I is a short horizontal tube or central hub,

-having three short tubes, A, B', and C', pro- ]'ecting radially therefrom iu different directions, as shown, the tube A being connected by the elbow A2 to the bottom of the cylinder A, the tube B to the -bottoin of the cylinder B, and the tube C by the elbow (t to the bottom of the cylinder C.

In the interior ofthe hub l are formed three circumferential grooves, a, I), and c, at about equa-l distances apart and surrounding the tube J, which passes through the hub l, accu rately fitting the same, and is adapted to have a column of, sugar-paste or other plastic ma terial forced through it in the direction indiv cated by the arrow, Figs. 2 and 3. The groove c connnunicates by the opening c with the y `tube A, Fig. 2, the groove b communicates b v the opening b', Figs. l and 3, with the tube B', and the groove c by means of the opening c', Fig. 2, with t-he tube C. Three series of holes, a?, Z, and ci, are drilled through the sides ot' the tube J, an d communicate, respectively, with the three grooves a., b, and c.

The cylinders A, B, and C being filled with paste ofthe proper consistency, and each cylinder containing a different color, it' the driving mechanism be set in motion to revolve the screws E E E in the proper direction the paste contained in the cylinder A will be gradually fed downward through the elbow Ai, tube A', and opening c into the groove a, and thence through the holes at and deposited iu lines or stripes upon the exterior of a column of paste which is being fed through the tube J. In the same manner the paste in the cylinder B vwill be fed down through the tube B and open- IOO which passes through the tube .l will issue therefrom 'having upon its exterior surface a series of longitudinal stripes of different colors arranged at such distances apart and in Y*may be desired.

such order as may be determined by the position of the holes a', If', and ci in said t-nbe J.

The number, width, or circumierential order of the stripes may be varied by changing, respectively, the number, size, or position ofthe holes a2, lr', and ci, and the colors may be varied as desired. l'n the apparatus shown in the drawings three cylinders are employed, but one, two, or more may be employed, as The machine as"shown in Figs. l, 12, and 3 is adapted for producing fifteen stripes ot' three different colors, five stripes of each color, the arrangement ot' said stripesbeing indicated in Fig. 7, which represents an enlarged end view of a stick ot' confectionery, the stripes being equal distances apart and the colors arranged in regular suecession around the circumterence. The paste from the cylinder A, passing through the groove a and holes a?, produces the stripes au, the paste from the cylinder ll, passing through the groove I) and holes bf, produces the stripes If, and the paste from the cylinder (f, passing through the groove e and holes c`, produces the stripes c.

Figs. et, 5, and (i illustrate at an enlarged scale the method ot'introduci ng lines or stripes ot' one or more colors to the interior ot' a column ot' sugar-paste or other plastic material. A small tube, a", extends diametrically across the'tube .'Ia'nd communicates at each end with Vthe groove a.V The tube a* is provided with aA hole or opening, c, in the center of its length, and concentric with the axis ofthe tube J, and with two other holes, c n, between the hole nf andthe ends ot' the tube ci. Two other tubes, al ci, extend inward toward the center of the tube .I at right angles to the tube a?.

rlhey are each provided at their inner ends with an opening, a, upon one side thereof, and communicate at their outer ends with` the groove u. The groove e also communicates with thc outer ends of four tubes, c4, projecting inward toward the center of the tube J, and each having an opening, c, upon one side at its inner end. The paste fed to the groove c passes into the tubes a" and ai, and is delivered at the openings wl an'd c into the interior of the tube J, and the paste from the groove c passes into the tubes 0*, and is delivered at the'openings o, and the column of paste which is being forced through the tube J, around the various small tubes above inentioned, will surround and envelop the lines of paste issuing from said openings, and be delivered from the tube J with a series of longitudinal stripes or lines of vone or more colors extendin through th e interior thereof. Stripes of different colors may at the same time be.

placed upon the exterior ot' the stick of paste by means of the openings communicating with the groove a, t-he openings b, communicating with the groove t, and the openings c?,

communicating with the groove c, in the manner as previouslydescribed. The design producedvby this special arrangement of holes and tubes illustrated in Fig. 8, and the operation is as follows: The paste which fed from the cylinder A to the groove ay will pass through the tubes a* and a7 and openings a5 and c, and form the four interior stripes ce, Fig. S, andthe centra-l interior stripe, c, while the paste which enters holes at will form. the 'four external stripes lr. The paste fed from the cylinder B to the groovev b will enter the openings b2 to form the eight exterior stripes b, and the paste't'e'd fromthe cylinder (l to the groove c will pass through the tubes c* and openings c5, and form the .tour interior stripes e, and the paste which passes through the holes 'c` will form the four exterior stripes c.

I have described the limrtienlar design which the machine as shown in the drawings is-adjusted to produce; but it is obvious that the number and position ofthe tubes for pro ducing the internal stripesmay be varied, the number, shapes, and sizes of the openings in said tubes may be changed, the colors ofthe paste may be varied as desired, and an almost unlimited number ot' combinatitms and designs produced.

The tube J is adapted to be connected with a suitable machine arranged to force paste through said tube, as is illustrated in Fig. 3. Upon one end ofthe tube J` is secured the iiange j', surrounded by the swivel coupling-ring g, whiclrmay be screwed upon the end ofthe horizontal cylinder' or tube l( to connect the tube.)r therewith. A portion of a vertical cylinder, Il, is shown, provided with a suitable screw, M, for lorcing the paste contained therein downward to the screw N, arranged to force the paste through the horizontal eylinder l, in substantially the same manner as shown and described in either of two other applications of mine of even date herewith. My present invention is applicable to either ofthe machines shown and described in the applications referred to.

The tube J is provided at its outer end with the screw-thread h for the purpose of attaching thereto a device for twisting the sticks oi' plastic material, which device may be conu strueted on the same principle as the one shown and described in Letters Patent No. 194,954, granted to me September 1], 1877.v A shoulder, fi, is formed upon the tube .I a means of fixing the proper position o't' said tube within the hub I by coming in contact with the end of the hub I when the series of openings in the tube .I are opposite therespective grooves in the hub I.

In Fig. 9 is illustrated amethod of coating the entire surface of a stick ot' sugar-paste oi' one or more colors with paste of another color, instead of covering it partially by striping, as before described. In this case only one ofthe cylinders A, B, or G would be used-as, for instance, the cylinder B. rEhe tube J is divided at-'a point within the hub I where the IOO IIO

groove bv is situated, and the ends are separated, as shown, so that the groove b communicates throughout its entire circumference with the interior of the tube J, and the paste fed into the groove b willsurround the col-v umn of paste passing through the tube J, and deposit upon the entire surface thereof a coating of even thickness. The openings through inders or receivers provided with means for forcing the matcrialtherefrom, in combination withv the tube J, thehub I, provided with one or more grooves or annular spaces surround ing said tube, and communicating therewith and with said cylinder or cylinders, and means of forcing plastic material through the tube J, substantially as and for th e purposes descri bed.

2. ln a machine for working, shaping, and combining plastic materials, one or more cylw inders or receivers provided with means for forcing the material therefrom, in combination with the tube J, the hub I, provided with one or more grooves or annular spaces communicating with said cylinder or cylinders, one or more tubes projecting into the interior of the tube J, communicating at their outer ends with said annular space or spaces, and cach having one or more openings upon one side thereotwithin the tube J, and means of forcing plastic material through. said tube J, substantially as and .for the purposes described.

In a machine for working, shaping, and combining plastic materials, one or more cyl inders or receivers provided with means for forcing the material therefrom, in combinati on with the hub I, provided with one or more grooves or annular spaces, each communicat ing with one of said cylinders, the tube J, pro vided with one or more orifices, ai, b2, or c, one or more tubes projecting into the interior of the tube J, and communicating with said groove or grooves, and also with the interior pf the tube J, by one or more openings in eachV ofsaid tubes, and means for forcing plastic materi al through said tube J, substantially asand for the purposes described.
